I've recently completed the game 100% going through all 96 exits again and that inspired me to make this topic.
Since a lot of EoFFers have played Super Mario World before I'm thinking a lot of you will have an answer for this: Which level in Super Mario World do you find the hardest?
I have a hard time picking between the Valley Fortress, Outrageous, and Tubular. The Valley Fortress has way too many spikes and spike pillars which makes dying insanely common. Outrageous has so many hazards to watch out for like flame snakes, Bullet Bills, Flying Hammers Bros, and Pirahna Plants that shoot fireballs. Tubular has Charging Chucks throwing balls at you and Volcano Plants shooting fire while floating as a Balloon, meaning one touch will kill you since you have to fly through the level to survive (though being Caped and having the Blue Yoshi make things insanely easier).
